16 Claims.

This invention relates to combined typewritin and computing machines,as, for example, an Underwood, in which numbers typed upon a work-sheetare also computed. The invention relates more particularly to automaticprinting devices and provides novel features of type-train actuation andthe automatic control thereof, which are an improvement over theinvention shown in the pending application of Leo Starck, Serial No.579,191, filed December 5, 1931 (now Patent No. 1,932,646, dated October31, 1933).

The present invention is herein illustrated as embodied in a' machineusable for making out bills in which the different items are enteredline by line and dated at the beginning of each line. For dating eachitem according to its entry-date, there may be used a specialtype-device as shown, for example, in the patent to Henry Resch, No.1,512,310, of October 21, 192 i. The usual typetraln to whichsaidspecial type-device may be attached is brought into actionautomatically for dating a new item or line upon a bill, said automaticaction being initiated upon typing of the last figure or letter in thepreceding line or item of the bill. As shown in said pending applicationof Starck, and in the patent to De Haven & Schaaf, No. 1,432,678, thecarriage is causedto be automatically returned after printing said lastnumber or figure, the return being effected by an electric motor. 1 Thecarriage is automatically arrested at the end of its return movement,and the platen is automatically line-spaced preparatory to beginning thetyping of a fresh line.

When the carriage thus reaches the beginning of a line, the next step isto cause the date to be printed. The third step is to then cause thecarriage to jump or tabulate to the point of beginning the entry for thetyping of the next item.

An object of the present invention is to provide for normal action ofthe date-printing typebar train, and is attained by novel meansoperative to impart an impulse to such train so as to have the sameeffect as finger-operation thereof. Accordingly the date-printing trainreceives a momentary impulse suflicient to cause normal printing impactof the type-bar, the novel means providing that said impulse ismomentary in order to allow a normal rebound of said type-bar to itsusual restored position. The letter-feeding or space-skipping operationof the carriage may thus ensue normally and need not be delayed for thereturn of the type-bar train, as has heretofore been the case when suchreturn depended on comnism is started at a moment coincident with thesettling of the carriage into drop-back position. It will be understoodthat said drop-back position is the position attained by the carriageafter it strikes the usual return stop. By thus timing the operation ofthe date-printing train, any chance of printing the date out of place onthe work-sheet is avoided.

Other features and advantages will hereinafter appear.

Keys 10, when depressed, swing type-bars 11 against a work-sheet on aplaten 12 to print The numbers are printed by keys 17, and are indexedor set up on a mechanism, outlined at 18, and subsequently run into atotalizer 19, Figure 1. Pendants 20 rock shafts 21 to actuate a linkage22 to depress index-pins 23. The index-pins 23 on bars 24 are setseriatim as the typewriter-carriage 13 is fed. Carriage-tappet 25actuates jack 26, link 27 and transposition device 28 to move thedenominational bar 24 forwardly, as more fully described in Patent No.1,280,065, to Minton.

A general operator 29, driven by motor 30, drives bars 24 anddial-wheels, as in patent to Thornton, 1,146,371.

The cycling motor may be automatically set off as the carriage completesits traverse of a computing zone, by the usual dog (not shown) that issettable on a carriage-rack 73, and depresses the usual motor-trip lever32 to release the motor-clutch 38 for cycling the machine. Thetrip-lever 32 when operated raises the usual link 33 to rock thebell-crank 34 and move a holding arm 34*- out of the path of a lever 35,to permit spring 36 to swing the lever 35 about its pivot and depressthe slide 37 to release the clutch 38, thereby causing the machine to becycled.

The automatic carriage-returning mechanism is fully described in theaforesaid application of Starck, and only such parts are herein shown asare necessary to illustrate the present invention. A projection 40 onthe traveling carriage 13 depresses a pawl 41, mounted on the lefthandmargin-stop 42, when the carriage encounters said margin-stop 42 at theend. of its forward travel. A margin-stop rack 43, loosely mounted oncross-shaft 44, is thereby swung about said cross-shaft and depressesthe carriage-return-engaging link 45. This causes, by means not hereinshown but described in said Starck application, the carriage 13 to bereturned to the right-hand margin-stop 46. Adjacent said right-handmargin-stop 46, and shiftable therewith, is a dog 47 splined to thecrossshaft 44. The carriage-projection 40 depresses the end of said dog47 as the carriage reaches the right margin-stop 46, thereby causing thecross-shaft 44 to be rocked for disengagement of the carriage-returningmechanism, as also shown in said Starck application, the connections foreffecting the carriage-return disconnection including an' arm 48, keyedto said cross-shaft 44, and a connecting link 49. The automaticcarriage-returning mechanism thus briefly described is effective toreturn the carriage, so that the usual carriage-abutment 50 strikes theright margin-stop-abutment 51, after which the carriage drops back, sayone and a half letterspaces, as determined by the amount of movement ofthe loose escapement-dog 14*.

It will be understood that the right marginstop 46 may be so set that asthe carriage 'settles in its drop-back position, the work-sheet columnin which the-date is to be printed is at the printing point, as shown inFigure 4. The automatic date-printing device is now brought into action,and will now be described.

A special type-bar 52 has a removable typecarrier 53, so that the typemay be changed ac- V cording to the date. Said special type-bar 52 is.usual connections, including bell-crank 56 and key-lever 57. Rotationof a rock-shaft 58 at the rear of the typewriter is utilized to actuatethe date-printing type-train, said rotation occurring as part of theoperation of the computing-machine-cycling mechanism, operable by themotor 30 through'the clutch 38. As said cycling mechanism operates, thegeneral operator 29 starts forwardly as indicated by arrow, Figure 9.The side of a notch 60 in said general operator thus forces a bell-cranklever 61 to rotate, and thereby shift a link 62 rearwardly, said linkbeing connected to a bell-crank 63, which, in turn, engages an arm 64,fast to said rock-shaft 58. Thus, by to-and-fro movement of the generaloperator 29, the rock-shaft 58 is rotated. Said rock-shaft completes itsrotation in one direction as soon as the general operator 29 startsforwardly, and is not restored to its original position until saidgeneral operator has reached the end of its return movement, thebellcrank lever 61 being unable to swing back until its end may dropinto the notch 60 at the end of said return movement of the generaloperator. The to-and-fro movement of the general operator 29 and henceof the rock-shaft 58 requires a substantial time-period, and it isundesirable to keep the date-printing type-bar in operated positionagainst the platen during this interval. For imparting a brief impulseto the date-printing type-bar train, the following mechanism isprovided. Fastened. to the rock-shaft 58 is a downwardly-extending arm66, whose lower end, having thereon a tab 67, may, through theoscillation of said rock-shaft 58 move forwardly and rearwardly. Saidtab 67 may thus become effective to move forwardly a link 68, carrying aspring-pressed pawl-member 69 against which said tab 67 may abut. Forenabling the link 68 to be moved into and out of operative relation withthetab 67, it may be pivoted at 70 to an arm 71, fastened to a shaft 72.An arm 75, in line with the type-action bell-crank 56,

and also fastened to rock-shaft 72, may be connected to said bell-crankby a link 74. It will now be seen that a forward movement of the tab 67is effective, when the spring-pressed pawl 69 is opposite the tab 67 ofthe arm 66, to actuate the date-printing type-bar 52.

For automatically moving the link 68 and its pawl 69in and out ofoperative relation with the tab 67, the movement of the carriage isutilized by means of the following devices. A rock-shaft 76 may be-somounted in bearings 77 that an arm 78, fast to said rock-shaft 76, maybe actuated by a tappet 79, adjustably mounted on the carriage. Theaforesaid rock-shaft bearing 77 may be secured to a cross-bar of thecomputing-machine frame. In order that the tappet 79 may by-pass the arm78 in the return movement of the carriage, it may be formed as bestshown in Figures 3 and 5, and swingably mounted on its supportingbracket 81, which, in turn, is adjustably secured to a cross-rod 82,forming part of the carriage 13. A spring 83 yieldably holds said tappet79 against the bracket 81, and yields only as said tappet 79 overridesthe rock- 'shaft arm 78 without rotating the rock-shaft 76 during thereturn movement of the carriage. The bracket 81 may be so positioned onthe crossrod 82 that the tappet 79 has just overridden the arm 78 as thecarriage reaches its extreme return position. Before the carriage dropsback, the relative position of said tappet 79 and said arm 78 will thenbe as shown in Figure 5. As the carriage moves to its drop-back positionin a letter-feeding direction, the end of the tappet 79 engages the arm78, thereby causing rotation of the rock-shaft 76, and which rotation isutilized to bring the type-train-actuating link 68 into operativerelation with the impulse-delivering arm 66.. To this end, saidrock-shaft 76 may have fastened thereon a lever for connection by meansof a link 86 to the rearward end of the type-train-actuating link 68.Said lever 85 may have two arms, one arm for attaching a spring 84,which keeps said lever 85 and connected parts in normal position bymeans of a stop-pin 88. The other arm of lever 85 has a pin-and-slotconnection 87 to the upper end of the link 86. Said pin-and-slotconnection permits rotation of the rock-shaft 76, and hence freecarriage-movement, should the downward movement of the link 86 betemporarily obstructed, as, for example, when the tab 67 is under thepawl 69. In order to ensure that link 86 may move downward when free todo so, a spring 90, relatively weaker than the spring 84, may be appliedto the upper end of said link 86. Through the action of the strongspring '84, the parts are held in the relative position shown in' Figure1, wherein forward movement of the impulse deliverin'g arm 66 will haveno effect upon the date-printing train. A

carriage-propelling spring 91 is of course strong enough to overcome thestrong spring 84, so that when the carriage under the pull of saidspring 91 drops back after the carriage-return movement, the rock-shaft76 is caused to be rotated, the tappet 79, striking against the arm 78at this time, effecting such rotation. The relation of theimpulse-delivering arm 66 to the dateprinting train will then be asshown in Figure 2, wherein the tab 67 is opposed to the pawl 69. Foroffsetting this opposed relation of the pawl 69 and-the tap 67 after thedate-printing train has received an impulse sufiicient to cause it toprint, the link 68 may be caused to swing about its pivot-point 70, sothat the edge of the pawl 69. escapes the edge of the tab 67. To thisend, a projection 96 on the link 68 may encounter a cam 98, which cammay be interposed to effect such encounter by means of rotation of therockshaft 58, the same rotation that efiects the impulse to the type-bartrain. Said rock-shaft 58 may, therefore, have fastened thereto an arm100, from which may depend a link 101, guided at its lower end at 102,and carrying said cam 98. Said cam 98 may be adjustably secured to link101 by screws 103. It will be seen from Figure 2 that the relativepositions of the linkprojection 96 and cam 98 may be such that asubstantial movement, and hence impulse, may be delivered to thedate-printing train before said train escapes from the tab 67 tocomplete its printing stroke by momentum. Figure 9 shows the position ofthe type-bar relatively to the platen at the time of such escape. Indelivering this impulse, the impulse-delivering arm 66 will have movedfrom the position indicated' bythe dotted line 107, Figure 9, to theposition indicated by the full line. Further movement of said arm 66 tothe position indicated by the dotted.

line 108 may be idle, as far as the date-printing train is concerned.

The date-printing train having been set for operation, as indicated inFigure 2, the cycling mechanism is brought into action. This, too,occurs as the carriage 13 settles in its drop-back position after havingbeen returned against the margin-stop 46. For starting the cyclingmechanism into operation in this manner, there is employed a stop 110,settable along the toothed rack 73, carried by the carriage 13. In orderthat said stop may be efiective to actuate the triplever 32 for startingthe cycling mechanism only permit said pawl to override the end of thelever 32, as shown in Figure 7. This overriding by the pawl 115 occursas-the carriage nears the end of its return movement. After overridingthe lever 32 and before the carriage reaches its dropback position, thepawl 115, under the influence of its spring 117, will have interlockedagain with the stop 110, so that it is effective, during said drop-backmovement of the carriage, to actuate the lever 32, as shown in Figure 6.The lever 32 will thus be actuated as the carriage settles in itsdrop-back position, the relative position of said pawl 115 andtrip-lever 32 being then as shown in Figure 4. In this position theclutch 38 is caused to be tripped to operate the cycling mechanism,thereby rotating the rock-shaft 58 and actuating the date-printingtrain, as already explained. The date-printing train beingfree to escapeafter the type-bar has received sufficient printing momentum, it followsthat said type-bar after printing may rebound normally, whereupon thecarriage escapes, the pawl 115 passing from contact with the trip-lever32, thereby ensuring termination of the cycling op eration. As thecarriage thus escapes and proceeds in letter-feed direction, the tappet79 may override the arm 78. In doing so the rockshaft may be caused torotate and the tappetspring 83 may yield. Should downward movement ofthe link at this time possibly be obstructed, the pin-and-slotconnection 87 is effective to co-operate with spring '83 to permit saidoverriding of the arm 78. Furthermore, should the tab 67 on arm 66possibly be opposed to the pawl 69 in the return movement of said arm66, said pawl may yield, for which purpose said pawl may have acam-surface 92 and be provided with a spring 93.

In the machine in which the present invention is embodied, there isemployed a skip-rack-device 119, referred to in the aforesaid pendingapplication of Starck, and effective to automatically jump the carriage,after printing the date, into position for beginning typing of the item.

In employing the skip-rack-device 119, the re action between the teethof the escapementpinion 112 and rack 113 may be sufficient to causeseparation of said rack and pinion. To prevent this, there is employed arack-holding member 120, fastened to the typewriter-frame and ofsufficient extent to overlie a projection 121 of said rack during thetime that the skip-rack-device is within its zone of action, saidprojection 121 being positioned accordingly on said rack.

The rock-shaft 72 may be journaled in a bracket 122, which may besecured to the crossmember 123 of the typewriter-frame. For guiding thelink 68, at its rearward portion, against sidewise displacementrelatively to the arm 66, the construction may be as best shown inFigure 8. To this end, said link may have secured thereto a bar 124 toform a space 125 within which the lower end of arm 66 may move freely,and the sides of which space thus formed prevent relative displacementsidewise of said link 68 and arm 66. The bar 124 may carry theprojection 96. The link-member 68 may have formed thereon ears 126, onwhich the pawl 69 may be pivoted by means of a pin 12''! projectingthrough said ears, and around which pin the pawl-spring 93 may becoiled.

In the herein-described machine, the rockshaft 58 also serves to controlthe computing mechanism through the medium of the computing-mechanismarms 135, which are attached to said rock-shaft. Thus said rock-shaft58, which, as already explained, is actuated by the computing-cyclingmechanism, affords convenient means for attaching the arm 66.

The bearings 77, in which the rock-shaft 76 is journaled, may be securedto the cross-bar spanning brackets 137, which may be secured to thetypewriter-frame. On one of these brackets 137, there may be pivotallymounted, as shown in Figure 1, the bell-crank 63.

As the by-pass p'awl 115 overrides the motortrip lever 32, as shown inFigure 7, sufficient reaction may be afforded by the train of parts, ofwhich this lever is one end, by a spring 139, Figure 1.

The operation of the machine in which the invention is embodied is asfollows. A bill 130 and a balance-sheet 131, interleaved with acarbonsheet (not shown), are in place around the platen, Figure 3. Upontyping the last balance on the balance-sheet, the carriage will haveadvanced to the left margin-stop 42, thereby depressing pawl 41 and thussetting the powerdriven carriage-return mechanism into operation, thecarriage-return movement being accompanied by a line-spacing operationby means not shown, but described in the aforesaid Starck application.The carriage proceeds in its return movement until the carriage-abutment50 strikes the right-hand margin-stop abutment 51. The cross-shaft 44will then have been rotated, as the carriage-projection 40 hasencountered the dog 47 on said cross-shaft, to disconnect the carriagefrom its returning mechanism. As the carriage 13 nears the end of itsreturn movement, the tappet 79 will override the arm '78 Without causingrotation of the rock-shaft '76. Similarly the by-pass-pawl 115 on thecarriage-stop 110 will override the end of the motor-trip lever 32without operating said lever., After the carriage reaches the rightmargin-stop abutment 51, there is the usual recoil or drop-backmovement, depending upon the extent of movement of the loose dog 14 ofthe carriage-escapement mechanism. At the end of said recoil or dropbackmovement, the tappet 79 is effective to cause rotation of the rock-shaft'76, thereby causing the link 68 to be raised (see Figure 2), so that itmay be pushed forwardly by the arm 66, to effect operation of thedate-printing bar 52. At the same time, that is, as the carriage reachesthe end of its drop-back or recoil movement, the motortrip lever 32 willhave been operated, thereby causing arm 66 to swing forwardly and thecam 98 to be raised, so that the pawl 69 may escape from said arm 66just before said type-bar 52 reaches the platen. After said pawl 69, andcon sequently the link 68, to which it is attached, escapes said arm'66,the date-printing type-bar 52 completes its stroke by momentum to printthe date upon the work-sheet through a ribbon (not shown). The type-barmay then rebound freely, whereupon the skip-space-device 119 becomeseffective to jump the carriage intoposition, beyond the date-colurrm,for starting typing of the succeeding item;

Where a new bill-form is started, it is necessary to also type the monthin addition to the day. To this end, as set forth in said Starckapplication, the right margin-stop 46-may be temporarily set againstcollar 118. After typing the month thus at the beginning of a bill, saidright margin-stop 46 may be reset against collar 114.

It will be noted that according to the present invention, restoration ofthe type-bar is not dependent upon completion of the cycling operation.Neither, therefore, need the .escape of the carriage be dependent uponthe completion of *said cycling operation, and thus the date isautomatically printed and the carriage tabulated to position forprinting the first item almost immediately after initiation of thecycling operation, and substantially before said cycling operation iscompleted. It will also be noted that by providing means whereby thedate-printing train is conditioned and the cycling operation isinitiated only when the carriage has settled in its dropback position,all chance of printing the datefigure out of place on the work-sheet isavoided.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
